Description
One, technical field
The present invention relates to a kind of outdoor high voltage double power source vacuum breaker that is used for high-voltage dual power supply line.
Two, background technology
Now, many to Supply Security, the higher power consumer of reliability requirement, for guaranteeing the continuity of power supply, all adopt two-way 10kV high voltage source (high-voltage dual power) to power, can greatly improve the reliability and the fail safe of power supply, assurance equipment and personal safety.And adopt the power supply of two-way high voltage source, exist and how to carry out the problem that the two-way power supply switches and protects.After promptly one road power supply has a power failure, how to switch to another road power supply quickly and safely.At present, mainly contain following several scheme: (one) adopts many indoor high-voltage switch cubicles to realize the switching and the protection of high-voltage dual power.This is present most popular high-voltage dual power scheme, and it has scheme maturation, reliability height, flexible configuration, multiple functional advantage.But also have significant disadvantages: (1) investment is big.The cost of switch cubicle is very high, and realizes needing two above high-tension switch cabinets at least by dual power supply, and its cost obviously will be higher than other scheme.(2) floor space is big, needs to build special power distribution room, and is equipped with relevant auxiliary facility, and infrastructure investment is big.As in the big city, then cost of land, construction cost will exceed the budget by a great deal.And, then have the Construction Problems of power distribution room in the mining area.(3) environmental suitability is poor.High-tension switch cabinet general work temperature range need be taked the measure of heating at-5 ℃～+ 40 ℃ at severe cold area, increases maintenance cost.(4) interlocking and operation sequence complexity are easy to can't not realize the function of expecting because of not operating in operation sequence to cause.(5) realize the two-way isolated from power if dispose electric isolating switch,, then be easy to cause two-way power supply paired running or oppositely send electrification as long as circuit breaker fracture insulation fault (as vacuum interrupter gas leakage etc.) takes place.(2) adopt two outdoor high-voltage vacuum breakers and controller to realize the conversion and the protection of high-voltage dual power.This scheme is also used many at present.With preceding a kind of scheme ratio, on its cost greater advantage is arranged, easy for installation, volume is little, and adaptive capacity to environment is strong, and operating temperature range can reach-40 ℃～+ 40 ℃.The major defect of its existence is to realize two reliable mechanical interlockings of circuit breaker, and misoperation and vacuum interrupter gas leakage can cause two-way power supply paired running or oppositely send electrification; Do not have isolation fracture behind the breaker open operation, need other configuration isolation switch to realize the maintenance and the maintenance of circuit.In addition, the reliability of electronic devices and components also is a big factor of its safe operation of restriction.(3) adopt three station SF6 on-load switches to realize the conversion of high-voltage dual power, cooperate fuse to realize protection simultaneously.This scheme is a kind of newer dual power supply scheme that proposes for the defective that solves second kind of scheme existence.Its cost is lower than alternative plan, and installs more convenient.Owing on a switch, realize the conversion of duplicate supply, therefore reliable mechanical interlocking is arranged in theory, can stop two-way power supply paired running and oppositely send electric possibility, be the higher a kind of scheme of present security performance.But realize based on on-load switch owing to it, can't realize short-circuit protection, therefore must join fuse and realize short-circuit protection.And not having tangible isolation fracture, the configuration isolation switch is realized line maintenance and maintenance separately.
Three, summary of the invention
In order to overcome the defective that existing high-voltage dual power power supply plan exists, the invention provides a kind of outdoor high voltage double power source vacuum breaker based on outdoor high-voltage vacuum breaker.This outdoor high voltage double power source vacuum breaker energy automatic or manual is realized the switching of duplicate supply; Have overcurrent, inrush phenomenon, short circuit, under-voltage, over-voltage protecting function; Need not independent configuration isolation switch can overhaul and safeguard circuit; Isolate fully on the two-way high voltage source is electric, can fine safety at the protection dual power supply system, prevent to cause two-way power supply paired running or oppositely send because of reasons such as misoperation or equipment faults.Under the worst case, even utmost point vacuum interrupter gas leakage can not cause two-way power supply paired running or the anti-phase electrification that send yet.
The technical solution adopted for the present invention to solve the technical problems is: a kind of outdoor high voltage double power source vacuum breaker, it comprises the three-phase outdoor high-voltage vacuum breaker, voltage transformer, current transformer, isolating switch, automatic controller, in the base of waterproof voltage transformer is housed, dress three-phase outdoor high-voltage vacuum breaker on the base, current transformer all is equipped with in the outlet both sides under the three-phase outdoor high-voltage vacuum breaker, current transformer is connected with isolating switch, the mechanical interlocks with three-phase outdoor high-voltage vacuum breaker and isolating switch also is equipped with in three-phase outdoor high-voltage vacuum breaker both sides, the main shaft of both sides isolating switch is connected by gangbar, tripper is housed on the gangbar, one side isolating switch spindle end head dress inspection operation handle, adorn electronic arrangement of clutch on the opposite side isolating switch main shaft, the manual operation handle is equipped with in its end, and electronic arrangement of clutch and drive motors pass through gears engaged.
This outdoor high voltage double power source vacuum breaker utilizes its symmetrical structure by a three-phase column support type outdoor high-voltage vacuum breaker, and the electric isolating switch of interlock all is equipped with in its both sides.The two-way high voltage source by the electric isolating switch inlet wire of interlock, is exported by vacuum circuit-breaker respectively then.Under the normal condition, have only main electricity side isolating switch to close a floodgate, opposite side isolating switch separating brake has guaranteed the isolation fully on the two-way power sourced electric.Inrush phenomenon, overcurrent, short circuit, under-voltage, overvoltage protection cooperate vacuum circuit-breaker to finish by automatic controller.Therefore have very high fail safe and reliability.Be convenient maintenance, this outdoor high-voltage vacuum double-power supply breaker spy is provided with release mechanism, can under the vacuum circuit-breaker gate-dividing state two isolating switches be opened simultaneously, satisfies the needs of line maintenance.After a side power supply dead electricity, the vacuum circuit-breaker separating brake, the selection of circuit is finished in the isolating switch action, and vacuum circuit-breaker closes a floodgate and can realize normal power supply then.The selection of two-way power supply with switch and can realize by automatic controller, also can be by manually carrying out.Electronic arrangement of clutch is housed on the isolating switch main shaft, and when manual operation, the arrangement of clutch clutch is to satisfy the manually operated requirement of double power source vacuum breaker.It has satisfied dual power supply user's demand better, realizes the safety of high-voltage dual power power supply and reliable to greatest extent, protection equipment and personal safety.And reached save investment, reduce land seizure, the purpose of protection environment.
